I Hit My Head—Should I Go to the ER? Here’s How to Know.
You know that moment. Your head hit something hard—a fall, a collision, an accident. Now you’re wondering: is this serious? Should you go to the emergency room, or is this just a bump that will be fine tomorrow?
Stop. Head injuries can be tricky because the most dangerous ones don’t always hurt the worst. Here’s exactly how to know if you need the ER.
Here’s the critical answer: Go to the ER if you lost consciousness (even for a second), if you’re vomiting, if you have a severe or worsening headache, if you’re confused or can’t remember what happened, or if your pupils are different sizes. Brain bleeds can develop hours after impact—when in doubt, get a CT scan. Head injuries are one area where “wait and see” can be dangerous.
Watch at Home vs. ER: What’s the Difference?
Not every bump on the head needs the emergency room. But some head injuries that seem minor can actually be serious. The key is knowing what warning signs to watch for. Our head trauma and concussion specialists see these situations daily.
Here’s how to assess whether your head injury needs the ER:
L — Loss of Consciousness: Did you black out, even briefly? Emergency sign: Any loss of consciousness warrants ER evaluation.
O — Observable Changes: Are you acting differently? Emergency signs: confusion, memory problems, slurred speech, unusual behavior.
C — Concerning Symptoms: What symptoms are you having? Emergency signs: vomiting, severe headache, unequal pupils, clear fluid from nose/ears, seizure.
If you have any of these emergency signs, go to the ER. A CT scan can detect bleeding or swelling that isn’t visible from the outside.
Brain bleeds (subdural and epidural hematomas) can develop hours after a head injury. Someone can seem fine initially, then deteriorate. This is why monitoring for 24-48 hours is critical, and why any new or worsening symptoms should prompt immediate ER evaluation.
When a Head Bump Can Be Monitored at Home
Some minor head injuries can be safely watched at home. Here’s when home monitoring may be appropriate—but always have someone check on you regularly.
Head Injuries That May Not Need Immediate ER
No loss of consciousness • Alert and oriented • No danger signs
The key is no danger signs and close monitoring. If you’re alone, can’t have someone check on you, or are uncertain—go to the ER.
When a Head Injury Needs the ER Now
These symptoms after a head injury are emergencies. Our emergency care team says these need urgent CT scan evaluation:

Emergency
Loss of Consciousness
Any blackout, even for seconds, indicates the brain was affected. This needs CT evaluation to rule out bleeding.

Emergency
Vomiting
Vomiting after head injury—especially repeated—is a sign of increased brain pressure. Go to the ER immediately.

Emergency
Severe or Worsening Headache
Severe, worsening, or “worst headache of your life” may indicate brain bleeding.

Emergency
Confusion or Memory Loss
Not knowing where you are, what day it is, or not remembering the injury indicates brain dysfunction. Altered mental status always requires evaluation.
Special Considerations
Always go to the ER if: you’re on blood thinners, you’re over 65, or the injury involved high speed, height, or significant force. When in doubt, get a CT scan at a 24-hour emergency room.
